If you're someone who lives, eats and breathes via their star sign, hoo boy, do we have some potentially earth-shattering news for you. (I say this as a Virgo who's just found out she's actually a Leo.)

NASA has declared that because of a shift of the Earth's axis, the zodiac needs to be re-evaluated. They explain that in the 3000 years since the zodiac system was drawn up, "the sky has shifted because Earth's axis (North Pole) doesn't point in quite the same direction."

This, combined with evidence of a long-suspected 13th zodiac sign, has led NASA to propose a new zodiac. And a warning, you may not be pleased with the result.

Capricorn: January 20 — February 16

Aquarius: Feb 16 — March 11

Pisces: March 11 — April 18

Aries: April 18 — May 13

Taurus: May 13 — June 21

Gemini: June 21 — July 20

Cancer: July 20 — August 10

Leo: August 10 — September 16

Virgo: September 16 — October 30

Libra: October 30 — November 23

Scorpio: November 23 — November 29

Ophiuchus: November 29 — December 17

Sagittarius: December 17 — January 20

The zodiac as we know it (or at least we thought we did before NASA came to the party) was established by the Babylonian people, a culture that first emerged in 1894 BC. The problem, according to NASA, is that the Babylonians did not "have any idea the Universe is so vast," and also ignored the 13th constellation when divising the zodiac system, likely for symmetry.

If you fall under the 13th sign, Ophiuchus? According to author of the Zodiac series, Romina Russell, you can be characteristed as "spirited, magnetic, impulsive, clever, flamboyant, and at times jealous, power-hungry, and temperamental."

The constellations are different sizes and shapes, so the Sun spends different lengths of time lined up with each one. The line from Earth through the Sun points to Virgo for 45 days, but it points to Scorpius for only 7 days. To make a tidy match with their 12-month calendar, the Babylonians ignored the fact that the Sun actually moves through 13 constellations, not 12. Then they assigned each of those 12 constellations equal amounts of time. Besides the 12 familiar constellations of the zodiac, the Sun is also aligned with Ophiuchus for about 18 days each year.
